Abstract
An ignition device () includes a power supply () for discharge; an AC power supply (); an ignition coil () for generating a secondary voltage in a secondary coil (B); an ignition plug () connected to the secondary coil (B); an AC electrode () electrically connected to the AC power supply (); a high-voltage electrode () located between the secondary coil (B) and the ignition plug (); an insulator () located between the two electrodes (); and a second insulator () which covers the ignition coil () and a capacitor () composed of the two electrodes () and an insulator (). The secondary voltage and AC power are supplied to the ignition plug () via the high-voltage electrode (). Thus, excellent ignition performance can be implemented while the occurrence of misfire is restrained.
